Legendary forgotten Kingdom of Lechia

Question

In the past I heard couple of legends about some mythic land in the north of Europe called Lechia. But after reading couple of articles about legendary Kingdom of Lechia I decided to find more information about this Kingdom. Below I listed some of them and I wonder, is it something real or should we think about it as a legend/mythology?

ANCIENT CITIES:

• Kodan (nowadays polish city Gdańsk) – 1750 BC -> confirmed by Pomponius Mela’s Map
• Gniezno – (nowadays polish city Gniezno) - 1700 BC
• Carodom (nowadays polish city Cracow/Kraków) – 1550 BC
• Szczyt (nowadays polish city Szczecin) – 1450 BC
• Vineta - legendary town in the north - more info

MEGALITHIC TOMBS:

• Słonowice - "Polish Valley of the Kings" - 4000 BC (older that Valley of the Kings in Egypt) and one more link

GENETIC CLUE:

• Haplogroup R1a (Y-DNA) - more info here

ROMAN CONNECTION:

• inscription - some info here

TERITORY:

• Sarmatia - info here
• Mare Sarmaticum (today Baltic see)
• and concept Sarmatism - well known in Poland

CERAMIC:

• Bronocice pot - 3400 BC - probably older wheel concept that Sumerian - more info here

So my question is about existence of this kind of civilisation in the ancient time. Is it real or myth?

Answer 1

Lechia is the mythological name for Poland, stemming from the word Lech (which is also a common first name).

According to legend, the name derives from the first ruler of Poland, Lech. It is also the derivation for the term Lechitic languages.
